The drawing refers to 5.42 mol of a monatomic ideal gas and shows a process that has four steps, two isobaric (A to B, C to D) and two isochoric (B to C, D to A).
(a) What is the work done from A to B?
(b) What is the heat added or removed from B to C?
(c) What is the change in internal energy from C to D?
(d) What is the work done from D to A?
